This instrument appears identical to all other magical harps. When played by a person proficient in the instrument, the player is able to cast one suggestion spell each turn of playing. Optionally, the DM can require a successful proficiency check be made to cast the suggestion. On a die roll of 20, the harpist has played so poorly as to enrage all those who hear.
Once per turn a bard is able to cause the harp to cast a command spell as a caster equal to the bard's level
